palette you choose will be applied to the Sonar Views.
• Gray: Light Gray (weak) to Black (strong)
• Green: Dark Green (weak) to Light Green (strong)

Bottom View selects the method used to represent bottom and structure on the display. See
What's on the Sonar Display: Sonar Bottom Presentation for more information.
Zoom Width adjusts the width of the zoomed view on the Sonar Zoom View, which is on the
left side of the display. See Views: Sonar Zoom View for more information.
83 kHz Sensitivity changes the sensitivity of the 83 kHz beam. Increasing the 83 kHz Sensitivity
will display additional weak returns, and decreasing the 83 kHz Sensitivity will display fewer
weak returns.
NOTE: 83 kHz Sensitivity is particularly useful for adjusting the sensitivity of the 83 kHz sonar returns
in the 200/83kHz Split Sonar View. The 83kHz sensitivity can be adjusted without affecting the
sensitivity of the 200 kHz returns shown in the 200 kHz sonar window.
